1,1 19,031. Specification of Letters Patent.

Original application filed June 6; 1913. Serial No. 772,055. Divided and this application filed: July 22, 1914.

' Serial No. 852,388.

i '0 all whom, it may concern Be it known that I, CHARLES H. Nou'rox, a citizen of the United States. residing at Worcester. in the county of lVoi-cester and State of Massachusetts, have invented a newand useful Steady-Rest for Use on Grinding-Machines and the like. of which the following is a specification.

This is a division of my application for patent on cylindrical grinding machine filed June 6, 1913, SerialNo. 7715.035. and relates to the steady-rest shown therein.

The principal objects of the in'venthm are to provide a steadya'cst ol :1 simplified form in which its contact with the work will be certain and positive and by which the friction of the moving parts will he reduced.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a plan of a steady rest constructed in accordance with this invention as applied to a grinding machine;- and Fig. 2 is a side elevation thereof showing its support in section.

The invention is shown as applied to. a grinding machine having a sliding table 5 provided with a support 6 thereon having a guiding surface or way 7 for the frame 8 of the steady-rest. This is provided with a screw having a handle 9 for clamping it. in any desired position along the guide or way '7. This steady-rest is shown as having an inclined body parallel with the surface of the guide or way on which it is carried and on this are pivoted parallel links 10 extending upwardly from the main frame of the steady-rest. These links carry a rigid arch'-shaped connectingmember 11 thus af-- fording a parallel mot10n.;. On this member is pivoted a lever 13 which has surfaces 14 arranged to provide two rigid bearing points that can engage the work C and hold it in position. Carried by the member 11 is an inclined screw 15.for engaging a rear projection 16 on this lever and adapted to swing the lever about its pivot so as to raise its work-engaging surfaces when the screw is forced in. mounted on the steacly-rest frame and en gages the member 11 to force it forward with a parallel motion when that screw is forced in. The end-of the lever 13 extends upwardly to constitute a handle for opera- A horizontal screw. 17 is,

tion by hand to force the lever back against the screw. This constitutes a simple and convenient way of ad usting the bearing surfaces of the steady-rest either horizontally or up and down, or both as may be. desired.

The adjustment is always easily accomplished and is positive in every way. It will be undcrstood,\()f course, that the work is held between centers supported by the table but not hereinshown.

Although I have illustrated and described only a single embodiment of the invention and shown it as applied to a specific grinding machine, I am well aware of the fact that it is capable of general use and that modifications can be made in its construction without departing from the scope of the invention as expressed in the claims. Therefore. I do not wish to-be limited in these respects, but

'hat I do claim is 1. In a steady-rest, the combination with a support. of a parallel motion connection mounted thereon. means for adjusting said connection toward and from the work, and.

for positively holding it in adjusted positions. and means on saidconnect-ion for engaging the work.

In a steady-rest, the combination with a support. of a parallel motion connection mounted thereon. means for adjusting said connection toward and from the work substantially horizontally, a lever pivoted on said connection and having work-engaging surfaces projecting from it, and means on said connection for positively adjusting said lever about its pivot for the purpose of forcing said work-engaging surfaces upwardly toward the work, and for positively holding it in adjusted positions.

3. In a steady-rest for a grinding -1naranged parallel with each other, member pivotally connected with the ends of piv'oted links extending upwardly there.- from parallel with each other, a ri id member connected with the ends of sai links at equal distances from their pivots on the support, a horizontal screw mounted on said support and engaging said rigid member to force it positively toward the work, a lever pivoted on the other end of the said rigid member and having surfaces for engaging 110- of said links, means for forcing said rigid member substantially horizontally toward the work, and means on said rigid member for engaging the work.

1 6. In asteady-rest, th combination of a slanting support, a pair f links pivoted to said supportand arranged parallel with eah otli'er, one being higher than the other, a rigid memberpivotally connected with the ends of said links,meansfor forcing said rigid member toward the work in a direction parallel with, said slanting support, and means on the rigid member for engaging the work.

7. In a steady-rest for a grinding machine, the combination of a support, a member movably mounted thereon, means for positively moving sald member toward the work and holding it in adjusted positions,

a work engaging member movably mounted on said support, and positive means for forcing the work engaging member toward the work and holding it in adjusted positions. I

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.

HOWARD W. DUNBAR, A. G. BELDEN.
